IMPROVEMENT IN LAMPS.

Specification forming part ot'Letters'Patent No. 40,094, dated September 29, 1863.

.To all whom, it may concern:

Be it known that I, M. B. DYOTT, of Philadelphia, in the county ot'Philadelphia and State of Pennsylvania, have invented a new and Improved Lamp; and I do hereby declare tha-t the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, making a part of this specification, in which- Figure l is a side sectional View ot' my invention taken in the line x x, Fig. 2; Fig. 2, a plan or top View of the same.

Similar letters of reference indica:e coircsponding parts in the two ligures.

This invention relates to that class of lamps These lamps should be provided with burners placed as low as possible, so as to be in close proximity to the oil in order to insure a good illuminatinglian1e, and when the lamp is not burning.

the oil, with a burner thus arranged, is liable to iiow trom the wick, which it ascends by capillary attraction', and run down the side ot' the lamp. To obviate this latter objection and to accomplish the result first nau1ed,I sink or depress the neck or top of the lamp so as to form a dripftrough or gutter around the collar, into which the burner is screwed, the drip trough receiving the oil, which may be drawn up the wick or spilled from the lamp, the neck of the lamp at the same time, by the formation of the drip trough or gutter, being of sufticient length or height to admit of the collar being rmly attached to it and be suiciently low to bring the burner quite close to the oil.

Besides this feature, the invention consists in constructing or forming the reservoir of the lamp with an indentation or hollow to partially receive the handle and still admit of the linger being readily passed through the latter, in order to carry the lamp or move it from place to place. By this arrangement the handle will not be liable to be broken otf nor the lamp upset.

To enable those skilled in the art to fully understand and construct my invention, l will proceed to describe it.

A represents the reservoir or body7 of the lamp, which is of oblate spheroidal form, and is provided with a neck, a, at the center ot' its upper part. This neck c is formed with a depression or hollow, b, all around it, as shown clearly in Fig. ,1, which causes the base of the neck to be below the top surface of the reservoir, and thereby admits of the neck being of suicient height to receive and hold firmly a metal collar, B, into which the burner is screwed, as usual.

By this arrangement or mode of construction the burner of the lamp, it will be seen, is brought quite close to the oil, and at the same time a drip trough is formed to catch the oil which is drawn up by the wick and ows therefrom,-so that no oil will run down the side of the lamp and be deposited upon the article or support upon which the lamp is placed. p

The reservoir A has a hollow or indentation, c, made in it at any point in its side, as shown in both figures, and in this hollow or indenta# tion the annular handle O is secured or attached. This hollow or indentation causes the handle O to be much less prominent than it would otherwise be, and still admits of the tinger being readily slipped through it when the lamp is to be lifted or carried from place to place. The handle, therefore, is not so liable to be broken ott' nor the lamp upset as when the handle projects the distance of its diameter from the prominent exterior surface of the reservoir.

The reservoir A may be constructed either of glass or metal.

Having thus described my invention, I claim, and desire to secure by Letters Patent, as an improved article of manufacture- A lamp made with a drip-trough depression, b, at its neck, and a handle depression or indentation, c, at its side, with attached handle C therein, all as herein shown and described.

M. B. DYOTT.
